An essential guide to assist those surveying for water voles, whether as a professional ecological consultant, a researcher or simply an interested amateur. This book provides detailed descriptions of all the habitats used by water voles, including ideal habitats as well as less typical places, with annotated photos to help the surveyor home in on just the right areas to look. It also contains a comprehensive photographic reference guide to assist in the correct identification of water vole field signs, and explains how to distinguish them from those of similar species. Tips on where and how to search for field signs are also provided, along with guidance on how best to record survey data.

The study was undertaken to examine the extent of women along with men participated in post-harvest activities; to identify the problems and constraints faced by them and find suitable solution from their perception. The post-harvest activities were estimated at farm level in Aman rice at Rangpur, Nilphamari, Khulna, Satkhira and Jessore district of Bangladesh by using survey data collected randomly from 270 rice growing households for the year 2012-13. It employed participatory approaches to investigate farmers’ perceptions on post-harvest management. The analyses shows women spends more time (591 hours ha-1) on PH activities than men (581 hours ha-1) but the ultimate decision maker of those activities are male indicating that women are very seldom given the opportunities to implement their ideas for execution although they are now gaining the right to give their opinion because of social awareness.J.

Background: Though Todd’s phenomenon (TP) is a relatively rare occurrence, its correct identification is of key diagnostic and therapeutic importance as a stroke mimic. Here we describe a case of isolated gaze palsy as a manifestation of TP, discuss periictal gaze abnormalities as lateralizing sign involving the frontal eye field (FEF), and present a narrative literature review. Methods: We reviewed the main features of the case and conducted a structured literature search of TP and gaze palsy using PubMed. We restricted the search to publications in English, Spanish, French, and German. Case presentation: A 71-year-old male with a history of right frontotemporal subarachnoid hemorrhage was admitted to the Emergency Department of our institution after suffering a first unprovoked focal to bilateral tonic-clonic seizure with ictal gaze deviation to the left. Cranial imaging showed no signs of ischemia, intracerebral hemorrhage, or tumor. The patient presented the following postictal features: involuntary eye deviation to the right due to left-sided gaze palsy and disorientation in time with preserved responsiveness. Eye movements were normal three days later. We concluded that the patient suffered from new-onset epilepsy due to sequelae following the right frontotemporal subarachnoid hemorrhage, affecting the FEF with contralateral ictal gaze deviation, and postictal gaze palsy with ipsilateral eye deviation as an unusual Todd’s phenomenon. Conclusion: Unusual manifestations of TP are uncommon but clinically highly relevant, as they can mimic stroke or epileptic status and are decisive in the diagnostic and therapeutic decision-making process. Though postictal gaze palsy has been reported associated with other deficits, this constitutes, to our knowledge, the first report of isolated gaze palsy as a form of TP. Further research into the underlying causes is needed. Ictal contralateral gaze and head deviation, and probably postictal ipsilateral gaze deviation if present, are very helpful for the lateralization of the seizure-onset zone.

The resurgence in interest in authoritarianism has been linked to a rise in the acceptance of right-wing ideology and also restrictions on civil liberties, particularly in relation to surveillance and the right to privacy. Whilst we can observe simple correlations between these variables, the dynamics of threat are more complex to understand. The analysis reported here demonstrates how the relationship between authoritarianism and the curtailment of civil liberties is moderated by the threat of terrorism. Using 2005 British Social Attitudes survey data, collected either side of the 7/7 bombings, comparisons between the pre-post samples indicate that the threat of terrorism activates authoritarian tendencies and reduces the protection of rights to privacy from government. Interestingly and importantly, reactions to terrorism in the form of a change in opinion regarding civil liberties for those scoring higher in authoritarianism remained almost constant between the two periods. The results provide support for understanding how minority opinions (removal of rights to privacy) can become majority views during times of threat.

This article proposes a vision-based method of determining in which of the three states, defined in the spin recovery process, is an aircraft. The correct identification of this state is necessary to make the right decisions during the spin recovery maneuver. The proposed solution employs a keypoints displacements analysis in consecutive frames taken from the on-board camera. The idea of voting on the temporary location of the rotation axis and dominant displacement direction was used. The decision about the state is made based on a proposed set of rules employing the histogram spread measure. To validate the method, experiments on flight simulator videos, recorded at varying altitudes and in different lighting, background, and visibility conditions, were carried out. For the selected conditions, the first flight tests were also performed. Qualitative and quantitative assessments were conducted using a multimedia data annotation tool and the Jaccard index, respectively. The proposed approach could be the basis for creating a solution supporting the pilot in the process of aircraft spin recovery and, in the future, the development of an autonomous method.

Abstract Mainstream parties in Western Europe are increasingly struggling to hold together their base of support. As a lens for exploring this changing electoral landscape, this article focuses on the growing share of the electorate that is cross-pressured between conservative and progressive attitudes on economic and cultural issues. It argues that a stable asymmetry characterizes Western European mass attitudes: while support for the left is common among voters with progressive attitudes on both issues, it is enough to be conservative on one issue to turn right. Analyzing survey data collected from 1990 to 2017, the study shows that cross-pressures are resolved in favor of the right and examines the trade-offs this poses to center-right parties. These findings contribute to debates on electoral dealignment and realignment and shed light on the electoral choices of the center-right.

AbstractTwo new species of spiruroid nematodes in birds from Kangean Island, Indonesia are reported: Diplotriaena anthreptis sp. nov. is found from the abdominal cavity of Anthreptes malacensis malacensis. The new species is similar to D. ozouxi, D. bargusinica, D. delta, D. isabellina and D. obtusa in the size of tridents and the length of spicules. However, it differs from the five similar species in the structure of the tridents, in the morphology of the right spicule, in the spicule ratio and in the size of the eggs. Acuaria irhami sp. nov. is described based on two male specimens from under the gizzard lining of Dicrurus hottentottus jentincki. The new species can be distinguished easily from all congeners except from A. microecae, in having equal rather than subequal or dissimilar spicules. However, the new species can be differentiated from A. microecae in the number of postanal papillae, in the median preanal papilla and in the length of the cordons.

Cucina, Walmsley, Gast, Martin, and Curtin (2017) raise an important issue in evaluating whether our current approaches for key driver analysis on employee opinion survey data are indeed best practices. As has been argued elsewhere (Putka & Oswald, 2016; Scherbaum, Putka, Naidoo, & Youssefnia, 2010), there is and can be misalignment between current and best practices. We agree with Cucina et al. that our field should engage in larger discussion of these issues. That discussion is critical, as industrial and organizational (I-O) psychologists are competing with those outside our field who have either little knowledge of best practices in data analysis (but who have been empowered by technology that automates the analysis) or little knowledge of psychology (but a great deal of knowledge in big data analytical techniques). I-O psychologists are in the vanguard of survey data analysis (Ducey et al., 2015), and we have a responsibility to maintain the standards of our field as well as to wield our influence to guide other practitioners outside our field on sound theoretical and analytical approaches.
